Automorphic Number

✹An Automorphic Number is a number whose square ends in the same digits as the number itself.

class Automorphic_Number
{
    public static void main(String[] args)
    {
        int n,sq,d=0,m;
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter the Number = ");
        n=sc.nextInt();
        m=n;
        sq=n*n;
        // Count Number of Digits
        while(m>0)
        {
            d++;
            m/=10;
        }
        // Checking the Condition
        if(n==sq%(int)(Math.pow(10,d)))
            System.out.println("Automorphic Number");
        else
            System.out.println("Not an Automorphic Number");
    }
